Yess, the reason was a sample for you on which I made a 60p project with a 30fps timelinesetting. My normal setting there is "Time & Frames".
@j-v - Uhuh . .A sample, which confused me more - not an unusual state for me to frequent.
Just select "Times & Frames" once for all your new projects as rulerformat and each Project has the right rulerformat.
@3POINT - Sure, this is what I had been doing - end of! - However, recently I was reading on the Forums that one of our VegHeads had issues with this and went away from T&F and I got my head turned. I then looked for the 60fps Format.
Anyways, Gents, I shall revert to T&F from now on.
